Abstract: An impact rotary tool includes a hammer, an anvil, an output shaft, a housing, and a bearing (first bearing). The bearing (first bearing) is held by the housing. The anvil includes a first contact portion. The output shaft includes a second contact portion. The second contact portion receives, from the first contact portion, force that causes the output shaft to rotate. The bearing (first bearing) is in contact with at least one of the first contact portion or the second contact portion and supports at least one of the output shaft or the anvil rotatably.
